Description

Technical Field

[0001] This invention relates to a correction device, and more particularly to a multi-axis dynamic scoliosis direction correction device, belonging to the field of medical device technology. Background Technology

[0002] As a core device for non-surgical treatment of scoliosis, spinal orthopedic braces utilize customized rigid or semi-rigid structures to apply continuous and directional pressure or traction to the scoliotic spine based on biomechanical principles. This aims to slow the progression of deformity and improve spinal alignment, and is especially suitable for adolescent idiopathic scoliosis patients with a Cobb angle of 20°-40°.

[0003] However, traditional spinal orthopedic braces have significant limitations: on the one hand, they are difficult to achieve "targeted traction" and often stretch the entire spine (including normal segments and curved segments) indiscriminately, which will have a negative impact on biomechanical balance, tissue damage risk and treatment effect; on the other hand, the tension needs to be manually adjusted regularly according to the characteristics of different people, which is not very convenient to operate.

[0004] To address this issue, a multi-axis dynamic scoliosis direction correction device was designed. Summary of the Invention

[0005] The main objective of this invention is to provide a multi-axis dynamic scoliosis correction device. A movable connector between the spinal plates, consisting of a first ball seat and a first ball bead, allows for precise fit and flexible adaptation according to the natural direction of the spine, ensuring accurate targeting of the deformed segment of the scoliosis and laying the foundation for subsequent targeted correction. Simultaneously, tension sensors on both sides of the spinal plates continuously monitor the pressure on the deformed segment, providing real-time data support for adjusting the corrective force. Furthermore, a hydraulic adjustment mechanism and a positioning support mechanism work synergistically. The hydraulic adjustment mechanism drives the spinal plates to adjust in a straight line, providing directional corrective force to the curved deformed segment. This design fundamentally avoids the indiscriminate stretching of normal spinal segments by traditional braces, reducing the risk of biomechanical imbalance and tissue damage, and significantly improving the targeted nature of the correction. The positioning support mechanism passively adapts to the adjustment of the spinal plate, providing stable support for the user's spinal segment, effectively maintaining the corrected state, and preventing the spine from bending backward due to force. In addition, the closed-loop control system composed of tension sensors and controllers can monitor the magnitude of the corrective force in real time and feed it back to the hydraulic pump. The pressure of the hydraulic chamber is dynamically adjusted through the injection pipe to achieve automatic fine-tuning of tension. This design replaces the manual adjustment mode of traditional braces, greatly reducing the difficulty of operation and improving the convenience of use.

[0006] The objective of this invention can be achieved by adopting the following technical solution:

[0011] Tension sensors are installed on both sides of the spinal plate. An elastic rope is provided between the tension sensors at opposite sides of the two sets of spinal plates.

[0012] The hydraulic adjustment mechanism is connected to the two sets of spinal plates and is used to drive the spinal plates to adjust in a straight line to provide directional corrective force;

[0013] The positioning support mechanism is located between the upper and lower arc-shaped plates. The positioning support mechanism works with the spinal plate to passively adapt the length as the spinal plate is corrected and to support the spinal segment.

[0014] The control system includes a controller, which is installed on the outside of the lower plate. The controller is electrically connected to the tension sensor and the hydraulic adjustment mechanism, and is used to control the action of the hydraulic adjustment mechanism according to the detection value of the tension sensor.

The lower plate is provided with a hydraulic oil supply assembly that communicates with the inside of the hydraulic chamber.

[0019] Preferably, the hydraulic oil supply assembly includes a through pipe, a hydraulic tank, a hydraulic pump, an injection pipe, a return pipe, and a switching valve. The through pipe is horizontally fixed to the side of the spine plate and communicates with the interior of the two sets of hydraulic chambers. The hydraulic tank is fixed to the outside of the lower plate. A hydraulic pump is installed at one end of the top of the hydraulic tank. An injection pipe communicating with the through pipe is installed at the output end of the hydraulic pump, and a one-way inlet valve is provided on the injection pipe. A return pipe is provided between the through pipe and the hydraulic tank, and a switching valve is provided on the return pipe. The controller is electrically connected to the hydraulic pump through a wire.

[0023] Preferably, the end of the pull rod located outside the fixed block is provided with a pull block.

[0024] The beneficial effects of this invention are as follows:

[0025] The present invention provides a multi-axis dynamic scoliosis direction correction device. The movable connector between the spinal plates is composed of a first ball seat and a first ball bead. It can achieve precise fit and flexible adaptation according to the natural direction of the spine, ensuring that the device can accurately lock the deformed segment of the scoliosis, laying the foundation for subsequent targeted correction. At the same time, the tension sensors on both sides of the spinal plates can continuously monitor the pressure of the deformed segment, providing real-time data support for the adjustment of the corrective force.

[0026] Based on this, the hydraulic adjustment mechanism and the positioning support mechanism work together. The hydraulic adjustment mechanism can drive the spinal plate to adjust in a straight line, providing directional corrective force for the curved deformed segment. This fundamentally avoids the indiscriminate stretching of normal spinal segments by traditional braces, reduces the risk of biomechanical imbalance and tissue damage, and significantly improves the targeted nature of the correction. Meanwhile, the positioning support mechanism passively adapts to the adjustment of the spinal plate, forming stable support for the user's spinal segment, effectively maintaining the corrected state and preventing the spine from bending laterally again due to force.

[0027] In addition, the closed-loop control system composed of tension sensor and controller can monitor the magnitude of correction force in real time and feed it back to hydraulic pump. By dynamically adjusting the pressure of hydraulic chamber through injection pipe, the tension can be automatically fine-tuned. This design replaces the manual adjustment mode of traditional brackets, greatly reducing the difficulty of operation and improving the convenience of use. Attached Figure Description

[0045] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0046] Example 1

[0047] like Figures 1-9 As shown, this embodiment provides a multi-axis dynamic scoliosis direction correction device, including an upper plate 1, a lower plate 2, a spinal plate 6, a movable connector, a tension sensor 10, a hydraulic adjustment mechanism 12, a positioning support mechanism 13, and a control system.

[0048] The upper patch 1 and the lower patch 2 are arranged parallel to each other vertically. The outer side of the upper patch 1 is provided with an upper arc-shaped plate 3 that surrounds the armpit, and the outer side of the lower patch 2 is provided with a lower arc-shaped plate 4 that surrounds the spine. A fixing mechanism 5 is provided between the upper patch 1 and the upper arc-shaped plate 3, and between the lower patch 2 and the lower arc-shaped plate 4.

[0049] When the device is worn, the upper arc plate 3 surrounds the armpit and the lower arc plate 4 surrounds the lower spine. The arc structure on the inner side of the upper plate 1 and the lower plate 2 conforms to the body contour. The fixing mechanism 5 connects and fixes the arc plate and the plate to ensure that the device fits the torso stably.

[0050] A spinal plate 6 is evenly arranged between the upper plate 1 and the lower plate 2. The upper plate 1 and the lower plate 2 are respectively fixedly connected to the spinal plate 6. A binding mechanism 9 is provided between the sides of the spinal plate 6.

[0051] The strap 901 passes through the through hole 902 of the spinal plate 6 and is secured by the Velcro 903 to fix the spinal plate 6 in the corresponding position of the spine, thus completing the initial locking of the deformed segment.

[0052] The movable connector is located between adjacent spinal plates 6. The movable connector includes a first ball seat 7 and a first ball 8 that rotates with the first ball seat 7. The first ball seat 7 is connected to one of the spinal plates 6, and the first ball 8 is connected to the other spinal plate 6.

[0053] The first ball seat 7 is made of 316L stainless steel, with a 0.5mm thick silicone damping ring embedded in the inner wall. The first ball 8 is made of zirconium oxide ceramic, with a diameter of 10-15mm and a 0.2mm gap with the ball seat. It can achieve ±45° multi-directional rotation with a rotation torque of 0.5-1N・m, ensuring that it is flexible and secure when conforming to the curve of the spine.

[0054] The spinal plate 6 can rotate in multiple directions through the first ball seat 7 and the first ball 8, and can flexibly adapt to the natural direction of the spine, precisely fitting normal and deformed segments.

[0055] Tension sensors 10 are installed on both sides of the spinal plate 6. An elastic rope 11 is provided between the tension sensors 10 at opposite sides of the two sets of spinal plates 6. The elastic rope 11 is in a taut state. The tension sensors 10 are used to detect the tension signal applied by the elastic rope 11 in the deformed segment.

[0056] The tension sensor 10 has a range of 0-500N, an accuracy of ±1%FS, and a sampling frequency of 10Hz. It is fixed to both sides of the spinal plate 6 2cm from the edge using M3 screws. The elastic rope 11 is made of medical-grade latex thread with a diameter of 3mm and an elastic coefficient of 50N / m. The initial tension is set to 50-100N. Different patients can select the tension level (50N for children, 100N for adults) through the menu on the controller 14.

[0057] The tension sensors 10 on both sides of the spinal plate 6 are connected by taut elastic ropes 11. When there is scoliosis, the spinal plate 6 in the deformed segment will change the tension generated by the elastic ropes 11 on the tension sensors 10. The tension sensors 10 detect the tension signal in real time and transmit it to the controller 14 to provide data for the adjustment of the corrective force.

[0058] The hydraulic adjustment mechanism 12 is connected to the two sets of spinal plates 6 and is used to drive the spinal plates 6 to adjust in a straight line to provide directional corrective force.

[0059] The positioning support mechanism 13 is located between the upper arc plate 3 and the lower arc plate 4. The positioning support mechanism 13 cooperates with the spinal plate 6 and is used to passively adapt the length and support the spinal segment as the spinal plate 6 is corrected.

[0060] During the adjustment of the spinal plate 6, the positioning support mechanism 13 moves synchronously to achieve passive locking of the support length, stabilize the support of the spinal segment, and prevent scoliosis from recurring after correction.

[0061] The control system includes a controller 14, which is installed on the outside of the lower plate 2. The controller 14 is electrically connected to the tension sensor 10 and the hydraulic adjustment mechanism 12 respectively, and is used to control the operation of the hydraulic adjustment mechanism 12 according to the detection value of the tension sensor 10.

[0062] After receiving the signal from the tension sensor 10, if the controller 14 detects an abnormal tension, it will control the hydraulic adjustment mechanism 12 to operate. According to the value set inside the controller 14, it will automatically inject hydraulic oil periodically to straighten the spinal plate 6 to a certain length without the need for manual periodic adjustment, until the data of all tension sensors 10 are normal (within the error setting range), and the spinal correction is completed.

[0063] Example 2

[0064] The solution in Example 1 will be further described below with reference to its specific working method.

[0065] In this embodiment, the fixing mechanism 5 includes a plug plate 501, a positioning hole 502, a slot 503, and a bolt 504. The plug plate 501 is fixed to the end of the arc plate. The positioning hole 502 is evenly provided on the plug plate 501. The end of the plate is provided with a slot 503 that mates with the plug plate 501. Both ends of the outer side of the plate are threaded with bolts 504 that mate with the positioning hole 502.

[0066] Local working principle: Depending on the user's body shape, the insert plate 501 at the end of the curved plate is inserted into the slot 503 at the end of the plate. By adjusting the insertion depth of the insert plate 501 (i.e., selecting different positioning holes 502), the contact range between the curved plate and the plate is changed. Then, the bolts 504 on the outside of the plate are tightened to make it fit into the positioning hole 502 of the insert plate 501, locking the relative position of the insert plate 501 and the slot 503, ensuring a stable connection between the curved plate and the plate, and improving the adaptability of the device.

[0067] In this embodiment, the inner sides of the upper plate 1, the lower plate 2, the upper arc plate 3 and the lower arc plate 4 are all arc-shaped, and shoulder straps are provided at both ends of the top of the upper arc plate 3.

[0068] Local working principle: The shoulder straps provide auxiliary fixation, ensuring that the device fits the torso stably.

[0069] In this embodiment, the binding mechanism 9 includes a strap 901, a through hole 902, and a Velcro 903. Both ends of the spinal plate 6 are provided with through holes 902. Both ends of the strap 901 pass through the inside of the through hole 902, and both ends of the strap 901 are provided with Velcro 903.

[0070] Local working principle: In order to avoid displacement during the correction process, the two ends of the strap 901 are passed through the through holes 902 of the spinal plate 6, wrapped around the torso, and then fixed by the Velcro 903 at both ends. In addition, the tightness of the strap 901 (the position of the Velcro 903) can be adjusted to ensure that the spinal plate 6 fits tightly with the spine, while avoiding excessive tightness that may cause discomfort, thus providing a stable initial tension environment for the tension sensor 10.

[0071] In this embodiment, the hydraulic adjustment mechanism 12 includes a hydraulic chamber 1201, a piston 1202, a second ball seat 1203, a second ball bearing 1204, a support rod 1205, and a hydraulic oil supply assembly. The hydraulic chamber 1201 is vertically opened at both ends inside the spinal plate 6. The piston 1202 is slidably arranged at both ends inside the hydraulic chamber 1201. The second ball seat 1203 is fixedly installed on the outer side of the piston 1202. The second ball bearing 1204 is rotatably installed inside the second ball seat 1203. The support rod 1205 is fixed between the second ball bearings 1204 inside adjacent spinal plates 6. The lower plate 2 is provided with a hydraulic oil supply assembly that communicates with the inside of the hydraulic chamber 1201.

[0072] Local working principle: When hydraulic oil is injected, hydraulic oil is injected into the hydraulic chamber 1201 through the hydraulic oil supply component, which pushes the pistons 1202 at both ends to slide along the hydraulic chamber 1201. The pistons 1202 are connected to the support rod 1205 through the second ball seat 1203 and the second ball 1204. Since the second ball 1204 can rotate in the second ball seat 1203, the support rod 1205 can adapt to the multi-angle rotation requirements of the adjacent spinal plate 6.

[0073] In this embodiment, the hydraulic oil supply assembly includes a through pipe 1206, a hydraulic tank 1207, a hydraulic pump 1208, an injection pipe 1209, a return pipe 1210, and a switch valve 1211. The through pipe 1206 is horizontally fixed to the side of the spine plate 6 and communicates with the interior of the two sets of hydraulic chambers 1201. The hydraulic tank 1207 is fixed to the outside of the lower plate 2. The hydraulic pump 1208 is installed at one end of the top of the hydraulic tank 1207. The output end of the hydraulic pump 1208 is connected to the injection pipe 1209, which communicates with the through pipe 1206. The injection pipe 1209 is provided with a one-way inlet valve. The return pipe 1210 is provided between the through pipe 1206 and the hydraulic tank 1207. The switch valve 1211 is provided on the return pipe 1210. The controller 14 is electrically connected to the hydraulic pump 1208 through a wire.

[0074] The hydraulic pump 1208 is a micro gear pump with a rated flow rate of 5 mL / min and an adjustment step of 0.1 mL, which can achieve fine adjustment of the straightening force in the 0.5 N level. The controller 14 has a built-in PID algorithm, which calculates the straightening force deviation (target value ±5 N) every 10 seconds based on the feedback from the tension sensor 10. The oil is dynamically replenished through the injection pipe 1209 to ensure that the length set for periodic straightening is within the range during straightening.

[0075] Partial working principle: The hydraulic pump 1208 draws hydraulic oil from the hydraulic tank 1207 and pumps it into the through pipe 1206 through the injection pipe 1209 with a one-way inlet valve, increasing the pressure in the hydraulic chamber 1201 and driving the piston 1202 to move outward, thereby realizing the "unfolding" (adjusting towards a straight line) of the spinal plate 6. When the device is worn, the hydraulic chamber 1201 is in a full state, opening the switch valve 1211. When the spinal plate 6 is installed to fit the spine, the deformed section will cause some of the hydraulic oil inside the hydraulic chamber 1201 to be squeezed out and enter the hydraulic tank 1207 through the return pipe 1210. Then the switch valve 1211 is closed. The process of spinal correction is the process of replenishing the hydraulic oil inside the hydraulic chamber 1201. When the hydraulic chamber 1201 is completely full, the spinal plate 6 is in a straight state, and the spinal correction is completed.

[0076] In this embodiment, the positioning support mechanism 13 includes a fixing block 1301, a sliding rod 1302, a sliding hole 1303, and a one-way locking component. The fixing block 1301 is fixed on both sides of the lower arc plate 4, and the sliding rod 1302 is vertically fixed on both sides of the upper arc plate 3. The fixing block 1301 is provided with a sliding hole 1303 that cooperates with the sliding rod 1302. The fixing block 1301 is provided with a one-way locking component to prevent the sliding rod 1302 from moving downward.

[0077] Local working principle: When the spinal plate 6 is straightened, the whole device will be stretched. At this time, the slide rod 1302 can slide upward. If it stops moving, the one-way locking component will prevent the slide rod 1302 from moving downward and resetting, so as to realize the one-way locking of the support length.

[0078] In this embodiment, the one-way locking component includes a mounting groove 1304, a trapezoidal insert 1305, a return spring 1306, and a serrated groove 1308. The mounting groove 1304 is formed inside the sliding hole 1303. The trapezoidal insert 1305 is slidably disposed inside the mounting groove 1304. A return spring 1306 is provided between the trapezoidal insert 1305 and the inner end of the mounting groove 1304. The outer side of the slide rod 1302 is uniformly provided with serrated grooves 1308 that cooperate with the trapezoidal insert 1305 along the length direction.

[0079] Local working principle: When the slide rod 1302 moves upward, the inclined surface of the serrated groove 1308 on its outer side presses against the trapezoidal insert 1305, causing the trapezoidal insert 1305 to compress the return spring 1306 and retract into the mounting groove 1304, allowing the slide rod 1302 to move upward. When the slide rod 1302 stops moving, the trapezoidal insert 1305 pops out under the action of the return spring 1306 and locks into the straight surface of the serrated groove 1308, preventing the slide rod 1302 from moving downward, thus achieving one-way locking of the support length.

[0080] In this embodiment, the one-way locking assembly also includes a pull rod 1307, which is slidably connected to the fixing block 1301. One end of the pull rod 1307 is fixed to the end of the trapezoidal insert 1305, and the other end extends to the outside of the fixing block 1301 to release the locking state of the trapezoidal insert 1305 and the serrated groove 1308.

[0081] Local working principle: Pulling the pull rod 1307 causes the trapezoidal insert 1305 to disengage from the serrated groove 1308, thereby releasing the lock and allowing the slide rod 1302 to move down, facilitating disassembly of the device or adjustment of the support length.

[0082] In this embodiment, the end of the pull rod 1307 located outside the fixing block 1301 is provided with a pull block.

[0083] Local working principle: The pull block at the end of the pull rod 1307 can improve the ease of operation.

[0084] Example 3

[0085] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0086] When wearing the device, the upper arc plate 3 is wrapped around the armpit and the lower arc plate 4 is wrapped around the lower part of the spine. The arc structure on the inner side of the upper plate 1 and the lower plate 2 conforms to the contour of the torso. Then, the insert plate 501 is inserted into the slot 503, and the corresponding positioning hole 502 is selected and locked with the bolt 504. At the same time, the shoulder strap of the upper arc plate 3 is used to help fix it, ensuring that the device is stable and fits well. The first ball seat 7 and the first ball bead 8 of the spinal plate 6 cooperate to achieve multi-directional rotation, which can flexibly adapt to the natural direction of the spine. Then, the strap 901 is passed through the through hole 902 of the spinal plate 6, wrapped around the torso, and the tightness is adjusted with the Velcro 903 to ensure that the spinal plate 6 fits tightly with the spine, completing the initial locking of the deformed segment.

[0087] During dynamic monitoring and correction, the tension sensors 10 on both sides of the spinal plate 6 are connected by taut elastic ropes 11. When scoliosis exists, the tension of the elastic ropes 11 changes in the deformed segment of the spinal plate 6. The tension sensors 10 detect this tension signal in real time and transmit it to the controller 14, providing data for the adjustment of the correction force. After receiving the signal from the tension sensors 10, if the controller 14 detects an abnormal tension (exceeding the set range), it will control the hydraulic adjustment mechanism 12 to operate. The hydraulic pump 1208 draws hydraulic oil from the hydraulic tank 1207 and pumps it into the through pipe 1206 through the injection pipe 1209 with a one-way inlet valve, and then into the hydraulic chamber 1201 inside the spinal plate 6, pushing the piston 1202 to slide. The piston 1202 is connected to the support rod 1205 through the second ball seat 1203 and the second ball 1204, driving the adjacent spinal plate 6 to adjust in a straight line (to adapt to multi-angle rotation requirements), providing directional correction force for the deformed segment. In addition, according to the tension sensor... The change in the value of 10, combined with the elastic coefficient of the elastic rope 11, is used to calculate the deformation length of the elastic rope 11, and then the adjustment angle between adjacent spinal plates 6 is calculated. In addition, the height of a single vertical adjustment is calculated. It is determined that the height of each linear adjustment is within the set range. During the adjustment of the spinal plate 6, the positioning support mechanism 13 moves synchronously. The slide rod 1302 is stretched and slides upward with the device. Its outer sawtooth groove 1308 squeezes the trapezoidal insert 1305 into the mounting groove 1304 and compresses the return spring 1306. When the adjustment stops, the trapezoidal insert 1305 pops out under the action of the return spring 1306 and is locked into the sawtooth groove 1308, preventing the slide rod 1302 from moving downward, realizing the one-way locking of the support length, stabilizing the support of the spinal segment to prevent lateral bending again. In addition, when the vertical height of the spinal plate 6 is fixed and adjusted periodically, the distance of vertical movement of the slide rod 1302 can also be detected by the distance sensor to ensure the accuracy of the vertical height adjustment of the spinal plate 6.

[0088] In the control system stage, the controller 14 forms a closed-loop control system with the tension sensor 10 and the hydraulic pump 1208. It monitors the value of the tension sensor 10 in real time and automatically fine-tunes the tension and the straightening height of the spinal plate 6 by dynamically adjusting the pressure of the hydraulic chamber 1201 (replacing the traditional manual adjustment). When the data of all tension sensors 10 are within the set error range, the hydraulic chamber 1201 is fully filled, the spinal plate 6 is in a straight state, and the spinal correction is completed.

[0089] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
